Well, I used it with a Melee specialist ( I tell you,
I am disappoint by spikes) with 5 Will.
I wanted to do a level comparison, but I noticed I never actually leveled PK beyond 40 (45).
Thus, I did a Will comparison:
The middle is the unsurprised base value:| Will | PK Level | Damage |
| 4 | 40 (42) | 26-58 |
| 3 | 40 (37) | 24-53 |
| 5 | 40 (45) | 26-61 |
| 6 | 40 (48) | 27-64 |
| 7 | 40 (52) | 28-68 |
For a comparison, at 5 Will, Telekinetic Punch deals 27-39 damage.
Also, I think currently Mutated dog leather boots with metal caps are better protection than pure metal boots?^^
